Pinellas County officials used a controlled burn Friday to clear dry brush from 6 acres at the north end of Fred H. Howard Park and reduce the chances of a wildfire later. The area had not been cleared of natural fuels for years, county engineering specialist Ed Lucas said. The burn was conducted between 10:15 a.m. and noon by the Pinellas County Environmental Land Management Division and was carried out by volunteers. Friday was picked for the burn because wind was expected to keep smoke out of residential areas, Lucas said. This weekend's high chance of rain also could help ensure that all portions of the burn are extinguished.
